Sounds like a baseball game. Actually it is about the real birds. I live in the ozarks and feed the birds / squirrels / everything. I have noticed that the Cardinal pair that always come to the feeder are the dominate birds. I always thought Bluejays were loud and aggressive but the cardinals keep the Jays run off until they are done feeding. One eats while the other patrols. When they are done - the three jays can then eat. Last come the sparrows and so on. On another note - do you know why birds don't pee? They use thier peckers to eat with.
